Abstract

L'invention porte sur un système d'imagerie ultrasonore tridimensionnelle qui comprend une colonne verticale (1), un ordinateur (3), ainsi qu'un échographe, un capteur spatial et un premier dispositif d'affichage (8) connectés à l'ordinateur (3) respectivement. L'échographe est pourvu d'une sonde ultrasonore (17). Le système d'imagerie ultrasonore tridimensionnelle comprend en outre une plaque d'équilibrage de gravité (2) montée sous la colonne verticale (1) et connectée à l'ordinateur (3), un second dispositif d'affichage (4) connecté à l'ordinateur (3), et une structure de support servant à soutenir un patient. La structure de support est montée sur une partie supérieure de la colonne verticale (1). La plaque d'équilibrage de gravité (2) est utilisée pour mesurer des informations de données de distribution de pression des pieds du patient, et envoyer les informations de données de distribution de pression des pieds à l'ordinateur (3). Après traitement des informations de données de distribution de pression des pieds, l'ordinateur (3) obtient des informations de données de position des pieds et des informations de données de position de point de gravité des pieds du patient, et envoie les informations de données de distribution de pression des pieds, les informations de données de position des pieds et les informations de données de position de point de gravité des pieds au second dispositif d'affichage (4), de manière que le second dispositif d'affichage (4) les affiche.
